Re: [PD] udpsend performance issue

Some follow-up on this:

• By bundling the data into few large packets instead of many small

packets (hence decreasing the overhead), indeed the blocking occurs much less frequently as Martin suggested, though it still occasionally occurs every once in a while. I am sending an OSC bundle of 100 osc messages every 20 milliseconds. This means less than 10 kB per packet, a packet every 20 milliseconds. It occasionally blocks for more than 2000 milliseconds

• The exact same bundle of OSC messages (i.e. the exact same UDP

packet to be sent) sometimes blocks and sometimes (most of the time) doesn't block, randomly.

you could try iemnet's implementation of [udpsend] as this is specifically targetted at doing a better job  when sending/receiving large number of data.

Thank you, I'll give it a try
